Gt15 vs GT17:

:yeahthat:

 

[centoproject]

quite the difference lol

 

[JustAndy]

Will be keeping my eye on this one

 

[Petento]

Looks very good so far dude will be watching

Very high spec build, should be fun.

Not sure why you're going for a 1.2 flywheel (16v, I guess, the 8v is indentical to the 1108 one and even uprated won't cope with turbo torque -- we know this from eggsperience) the 1.4 16v one seems to cope well enough.

Isn't an oil catch tank with a filter that breathes to atmosphere illegal for road use?

so i have a red sei turbo that came from Jersey and now your building one in Jersey, not only that but i had a silver turbo cinq before hand as well.. How weird!! Also, my mate has a rotting R5GTT, i been eyeing up the intercooler on that for a while lol.

small world!

edit: wondered when this thread would pop-up, been looking forward to reading about this build!! Should be a complete weapon when its finished

 

[cinquecentos 4 life]

very nice mate

 

[Honeymonster]

Thanks Chaps

Almost forgot:

5" Revcounter with Instrementation for oil pressure, oil tempreture, water temperature, Battery voltage and boost replacing the original unit. Then seperate EGT, innovate wideband AFR, small shiflight, Gtech performance meter and knockgauge.

Yes Blu crazy world isn't it.

R5 intercooler is a good fit as long as you don't care about the tow hook.

Sorry missed this, yes it's a 16v flywheel we don't even have a decent scrap yard here pretty much everything is crushed before anyone gets a chance to pull any decent bits off it unless you buy a whole car. Gazzaman was breaking Smilers car at the time I purchased the engine so he was kind enough to hang on for a bit and send me the flywheel on the pallet along with the diff and UT brakes. Shipping something as heavy as a flywheel to Jersey is very expensive so it was too good an opportunity to miss. I believe WOJ runs a 1.2 16v flywheel? so we'll just have to see. I think it will be OK with an upgraded clutch (which will be new not the one in the picture) and I'm not an overly aggressive driver these days.

As for the catch can it is baffled (hand full of wire wool ) so no oil will escape from the breather. Whether it's legal or not where you are I don't know but we don't even have an MOT.

Believe it or not all these parts have been collected on a tight budget through hours of searching and perseverance. It hasn't been cheap but has cost a lot less than it should of.

keep up the good work fella

Yes, I run 1.2 16V flywheel. For two reasons: one is that 1.4 was difficult to get (actually the one I got was supposed to be 1.4, had a few words with the seller about that ), two is that it turned out 190mm LuK clutch (I like them, it's a personal thing) was much cheaper. So far (38kkm) it holds fine

In fairness, I hear that Tricker has had no issues, either. Seems that it's not the actual amount of torque that causes the slip, but the exceptionally sharp torque spike the GT15 (at least) can develop. Of course, if you can remove that by any means, while not reducing the peak figure, you'll have a far more manageable car anyway.

well tbh my old cinq clutch only started slipping when i was running 20+ psi and that was on its original clutch (100k miles) bearing in mind that car was turbo'd for most of its life. My seicento still has the oem clutch fitted atm as well and is coping fine so far although i do have a 1.4 16v clutch waiting to go on. I'm sure the 1.2 16v clutch is more than upto the task tbh.

 

[fingers99]

I think it really does depend on how you chuck the torque at it.

Blue with an uprated clutch (of specification lost in the mists of time) would slip markedly for about 500 rpm at a point corresponding exactly to the torque spike (torque increased about 60% over 500 rpm or so) if you held a higher gear and booted it (in the best traditions of we've got the torque, let's use it!), while it would hold fine if you zipped through the gears.

Team Lloyd subsequently fitted 1.4 16v clutches and, IIRC, Martin's car was pushing out something like 140bhp and wrecking the odd driveshaft without the clutch showing any undue stress.

No figures in front of me, but it stands to reason that a decent 1108 turbo will put out a fair bit more torque than a NA 1.4 16v, even if it does have less flab to lug around.

Not sure what clutch/flywheel the 500 Abarths are using, but, if it'll fit, that would be the super safe option. Still, all said and done, it's a relatively easy swap if it shows signs of stress.

 

[blu73]

i touched on looking at a complete 500abarth box for my sei at one point but i only got as far as it wouldn't be easy (as in the casings are different and not just bolt on able). No idea whether the clutch/flywheel would be useable though. lewey seems to know alot on this subject but he rarely comes in our humble cento section.

Something you should look into in detail fingers for your t-jet conversion i keep hearing about.

 

[fingers99]

I'll just do it the easy way and buy a T Jet engine and box out of a 500 Abarth (uses the same old box as the PGT and Alfa 155). The other T Jets use a different (I think, 2 different!) 6 speed boxes, and at least one fitment seems to use equal length driveshafts, which would be a good thing, but engineering a cupless transmission would probably be just too difficult/expensive. Someone did offer me a bellhousing to fit a SuperFIRE (non tub) box to a T Jet, but that would be extreme abuse!

Selling the house, so when that's done I should be able to get all 3 projects underway, and something with 2 wheels begining with D..............
